Inequality - EUROMOD estimates

The tables show three key measures of income inequality - Gini coefficient, S80/20, and Atkinson index - across various income concepts, following the definitions from Eurostat:

• The Gini coefficient measures the degree of income inequality within a country, ranging from 0 (perfect equality, where everyone has the same income) to 1 (full inequality, where one person has all the income).
• The S80/20 ratio, also known as income quintile share ratio, calculates the ratio of total income received by the 20 % of the population with the highest income (the top quintile) to that received by the 20 % of the population with the lowest income (the bottom quintile).
• The Atkinson index allows for varying sensitivity to inequalities in different parts of the income distribution. It incorporates a sensitivity parameter (A) for which the higher the value, the more sensitive the Atkinson index becomes to inequalities at the bottom of the income distribution. It takes values from 0 to 1, where higher values indicate higher inequality.

All indicators are offered for different income components. All incomes are equivalised and negative values at the householed level have been set to zero.
